I'm seeing a different bootstrap failure from those already discussed:

It appears the build is ignoring the --with-gmp option passed to
configure. Since <gmp.h> is included in system.h, if you include system.h
you have to pass the right -I option corresponding to --with-gmp /
--with-gmp-include. (There are several other such configure options for
MPFR, MPC, CLooG, ISL, libiconv at least - whether they are relevant
depends on whether your code ends up including the relevant headers.)
Hi, sorry for the troubles! I am having difficulty seeing this fail on
my system. I built gmp from upstream, installed it, and pointed to
the install location with --with-gmp. Which stage does your build fail
at?
I am actually not totally sure how to respect the -with-gmp argument
in libcc1. auto* tools are not my strongest skill. ;)
I notice gcc/configure.ac I think just exports the variables to
Makefile.in from the main configure script. That what we should do in
this case?
Here is a patch I'm bootstrapping/regtesting now (but, with system gmp
installed). I've verified that with this patch stage1 libcc1 is built
without -Werror in flags, while stage2 libcc1 is built with -Werror.
If this passes bootstrap/regtest, is it ok for trunk (should fix
two bootstrap issues)? Is the
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg02936.html
patch ok too (that one already tested; another bootstrap issue)?

* configure.ac: Remove -Werror addition to WARN_FLAGS. Add
ACX_PROG_CC_WARNINGS_ARE_ERRORS and AC_ARG_VAR for GMPINC.
* Makefile.am (AM_CPPFLAGS): Add $(GMPINC).
(WERROR_FLAG): Remove.
(AM_CXXFLAGS): Use $(WERROR) instead of $(WERROR_FLAG).
* configure: Regenerated.
* Makefile.in: Regenerated.
So is this still relevant if we stop bootstrapping libcc1?
The patch is OK if it's still needed.
Thanks,
Jeff
